Antimony (Sb) and arsenic (As) are two hazardous metalloid elements, and the biogeochemical cycle of Sb and As can be better understood by studying plant rhizosphere microorganisms associated with Sb mine waste. In the current study, samples of three types of mine waste—Sb mine tailing, waste rocks, and smelting slag—and …
1. Introduction. Antimony (Sb) is one of the most commonly used metallic element, with global reserve of 1.9 million tons. According to recent report, almost 80% of Sb production was concentrated in China, Russia, and Bolivia (United States Geological Survey, 2021).By 2020, China was the leading producer of Sb worldwide, accounting for …
Antimony is recognized as a crucial material due to its extensive application in modern industrial fields. China is the largest antimony supplier and consumer in the world. However, few studies focus on antimony flows and stocks in China from a whole life cycle perspective.
Antimony (Sb) is a non-essential element for plants, animals, and humans. With increased anthropogenic inputs from mining and industrial activities, ore processing, vehicle emissions, and shooting activities, elevated Sb levels in the environment have become a growing concern. Despite of its non-essentiality, some plants can take up and …
Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries. Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst. Geologically, native antimony is rare, and it is mostly found in sulfide ores. The main …
may be taken up by plants and animals. The concentration of antimony in air ranges from a very small part of a nanogram (1 nanogram equals a billionth of a gram) in a cubic meter (m³) of air (ng/m³) to about 170 ng/m³. However, near companies that change antimony ores into metal or make antimony oxide, concentrations may be more than 1,000 ...
On the other hand, since most plants are optimized for a specific size fraction (≥ 75 µm) and the tailings of chromite plants are generally characterized by fine particles, a recurring problem ...

Antimony uptake varies widely among plant species, growing sites, and underlying substrate conditions (Table 1). Most commonly, the highest plant Sb …
The concentration of antimony in water bodies is closely related to mining activities, and the oxidation, weathering, leaching, and permeation of waste rocks and tailings containing antimony may lead to an increase in antimony concentration in groundwater (Qiao et al., 2023, Wen et al., 2023). Figure S2 illustrates the pathways and …

At the plant of the Consolidated Murchison Co. in the Transvaal, South Africa, where a refractory high-antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery …
Stibnite (Sb 2 S 3) is the primary Sb ore, with valentinite (Sb 2 O 3) widely occurring (Filella et al., 2002a, 2002b). Typical crustal abundances of Sb is reported as 0.2 mg kg −1 (Plant & Rainswell, 1983). Antimony concentrations are generally much lower than the corresponding values for As.
Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction …
Throughout the 1.3 ha site, homogenous concentrations of antimony and arsenic, a by-product of the operation, were found along 0–0.5 m-deep profiles. Maximum concentrations for antimony and arsenic were 5780 mg kg −1 dry tailings and 852 mg kg −1 dry tailings, respectively. Despite the presence of the contaminants and the low pH …
